FORECASTING LCD TV DEMAND USING THE FUZZY GREY MODEL GM(1,1)

Abstract

LCD TV is a rather newly developed product, with limited data available for sales of all panel sizes, and these are collected in a rather vague manner by some research institutes. Therefore, we propose using the fuzzy grey model GM(1,1) with fuzzy-input value to extrapolate the LCD TV demand with fuzzy-output value. By using the fuzzy grey model GM(1,1) we succeeded in forecasting LCD TV demands with limited fuzzy-input data, and carried out a sensitivity analysis to show its robustness for modeling.
